A Guide To UK Duvet Sizes And Tog Ratings


Duvet sizes are typically named based on the mattress size they are designed to pair. Whilst perhaps obvious, the measurements of the duvets are different to the respective mattresses.

Size Measurements in CM Measurements in Inches
Single Duvet 135 cm x 200 cm 4’5” x 6’6”
Double Duvet 200 cm x 200 cm 6’6” x 6’6”
King Size Duvet 230 cm x 220 cm 7’6” x 7’2”
Superking Size Duvet 260 cm x 220 cm 8’6” x 7’2”

 

Just because you’ve opted for a king size bed, doesn’t mean you can’t opt for a superking duvet. In fact this can be really cosy and a pretty cool look depending the style of your bed.

Tog Ratings Explained

The tog rating of a duvet is a measure of its warmth. Tog rating starts at 1.0 and typically goes up to 15, although it is possible to get duvets with a higher rating.

The higher the tog rating of a duvet, the warmer it is. Lower tog duvets are most suited to summer, high tog duvets most suited to winter, and those in between a good choice for spring or autumn. If for whatever reason you’ve no desire to buy multiple duvets, a duvet with a tog rating of 10 or so can be a safe bet year round.

Season

Tog Rating

Summer Duvet

1.0 – 4.5 tog

Spring / Autumn

7.0 – 10.5 tog

Winter

12.0 – 15.0 tog

 

A higher tog rating does not necessarily mean a heavier duvet. The weight of the duvet is dependent on the filling of the duvet, not the tog rating.

Duvets come with a range of different fillings such as feather and down, cotton, silk, wool or microfibre and other synthetic materials.
